Abstract

The invention relates to a polycarbonate paint for flexible or thin-film solar cells and a preparation method thereof. The ink is prepared from the following components in percentage by weight: 8-12% of polycarbonate resin solution (the solid content of polycarbonate resin is 1-10%), 0.0001-0.1% of nano aluminum powder, 0.1-1% of viscosity regulator and the balance of solvent. The product can be applied to the upper surface of the flexible or thin-film solar cell by a spray coating, silk screen printing, printing or any other technique to directly enhance the generating efficiency of the flexible or thin-film solar cell.

Description

technical field [0001] The invention relates to a polycarbonate coating for flexible or thin-film solar cells and a preparation method thereof. By using the coating to form a layer of light-transmitting coating on the light-incident surface of flexible or thin-film solar cells, the flexible or thin-film solar cells can be directly improved. s efficiency. Background technique [0002] Polycarbonate (PC) is a polymer with carbonate groups in its molecular chain. According to the structure of ester groups, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. Among them, the low mechanical properties of aliphatic and aliphatic-aromatic polycarbonates limit their application in engineering plastics. At present, only aromatic polycarbonate has been industrialized. [0003] Due to the special structure of polycarbonate, polycarbonate is an amorphous, odorless, tasteless, non-toxic and transparent thermoplastic polymer. It is the only plastic variety wit...
